BATH-'TU B.

SPECIFICATION forming part of Letters Patent N o. 557,289, dated March31, 1896.

Application filed May 6, 1895. Serial No. 548,202. (No model.)

To all whom it may concern.-

Beit known that I, ROBERT KNIGHT STORY, a citizen of the United States,and a resident of the city of Brooklyn, county of Kings, and State ofNew York, have invented certain new and useful Improvements inBath-Tubs, of which the following is a specification. My inventionrelates to improvements in bath-tub construction, and has specialreference to the manner of securing the several parts together and themeans employed to prevent the corrosion of the outer and inner metallicshells, as will be hereinafter more fully set forth and described.

In the drawings, Figure l is a perspective view of my improved tub. Fig.2 is a crosssection on line of flanges of outer shell, through which thebody-sections are secured by rivets or otherwise. Fig. 3 is a portion ofthe top flanges of outer and inner shells, showing manner of boltingthem together. Fig. 4. is a side elevation of tub, showing a strip ofmet-al inserted between the outer and inner shells on top of the bodysheet to equalize the surface of flanges.

In the drawings like letters indicate like parts.

The bathtub is composed of an outer shell of metal A, preferably iron orsteel, and an inner lining of sheet copper, aluminium ,brass, or zinc,or any other metal suitable for the purpose. The outer casing or shellis coated on its inner surface with a non-corrosive liquid or rust-proofsolution. The outer shell or main body of the bath-tub is constructed inthree sections, flanged all around at the outside edges, the joints Abeing either punched and riveted or lock-seamed together to form 4thebody of the t-ub.

The inner shell or lining Bis formed of three or more pieces securelypressed or secured to the outer shell, the seams being either solderedjoints or lock-seamed. The

upper portion or outer edge of said inner lining is iianged so as toconform to the upper ilanges on the outer shell.

The top flanges of both the outer and inner :shell are punched withsuitable holes and bolted together, so as to rmly secure them to eachother, thus making the outer shell and lining substantially one solidbody, as shown in Fig. 3.

Before bolting the top flanges of the inner and outer shells together,owing to there being an unevenness in the top flanges of the outer shellof the tub caused by the flanges of the head and foot sheets overlappingthe flanges of the main or body sheet of the outer shell, I insert andadd to the iianges on the intermediary body sheet between the flanges ofthe outer shell and inner lining a strip of metal of the properthickness and Width to even up or make' the entire surface of the top ofthe anges of the tub perfectly level and true, as shown in Fig. 4., sothat when the wooden rim is screwed thereon a Water-tight joint issecured without filling the space which would be otherwise left withcompounds which are not stable or durable.

The tub when thus completed is supported on metallic legs so attached tothe body of the tub as to conceal the joints and to support the tub asuitable distance above the ioor, so as to prevent the accumulationofdirt, rbc., under the same.

That I claim as new and of my own invention, for which I ask LettersPatent of the United States, isk

l. A bath-tub consisting of an outer metallic shell or casing made insections, flanged and secured at all points by rivets or lockseaming,the top flanges of both the head and foot sheets overlapping the iiangesof the intermediary or body sheet, securing the same together by meansof a rivet or screw passed through the thickness of metal where theyoverlap; and additional strips of metal, laid on and secured to the topanges of the intermediary sheet, whereby said flanges are reinforced andtrued up to the face-line of the top flanges of the head and footsheets, substantially as set forth and described.

2. A bath-tub consisting of an outer, shell made in threesectionsflanged and secured together by rivets or lock-seaming, the topiiangespof the head and foot sections over-` lapping the flanges of theintermediary section-and secured thereto, a non-corrosive rust-proofcoating on the inner side of the ence of two witnesses, this 1st day ofMay,

outer shell, and an inner shell acting as a 1895. lininfto theoutercasin r and attached thereto vby bts or otherwise,c substantially as setROBERT KNIGHT SFORY 5 forth and described.

In testimony that I claim the foregoing as my invention I have signed myname, in pres- Titnesses H. C. VAN VECHTEN, JAMES KNAUT.
